Title: Plant extract, compositions containing the same, method of extraction, and uses thereof
Inventor: XIE CHEN
IPC: A23L2/38
Filed: 2019-03-04
Abstract: SOLUTION: An extract from leaves of mulberry with water or alcohol is disclosed. The extract has an ICvalue for inhibiting α-glucosidase I at a concentration of less than 90 μg/ml. Preferably, the extract comprises 5-40% (w/w) of total imino sugars and 20-70% (w/w) of total amino acids. The extract is obtained by three extraction and purification steps, and may be used to reduce production of melanin for treatment of such ailments or diseases caused by pigmentation as a freckle, a chloasma, striae gravidarum, a senile plaque and a melanoma. The extract may be used also for controlling a blood glucose level.EFFECT: The extract contains a lower concentration of 1-deoxynojirimycin (DNJ), so that side effects of drugs may be reduced. Since the cost of producing the mulberry extract is much lower than that of producing the pure DNJ compound, the cost of treating hyper-pigmentation caused by ailments is greatly reduced.SELECTED DRAWING: Figure 1

Abstract: To form a device chip without deteriorating quality.SOLUTION: A wafer processing method for dividing a wafer in which a plurality of devices are formed in each region on a surface partitioned by division schedule lines into individual device chips comprises a polyolefin-based sheet arranging step, an integrating step, a dividing step, and a picking-up step. The polyolefin-based sheet arranging step positions the wafer in an opening of a frame and arranges a polyolefin-based sheet in a rear surface or a surface of the wafer and an outer periphery of the frame, the frame having the opening housing the wafer. The integrating step heats the polyolefin-based sheet and integrates the wafer and the frame via the polyolefin-based sheet by thermal compression bond. The dividing step forms a modified layer in the wafer by irradiating the wafer with a laser beam of a wavelength having permeability to the wafer along the division schedule lines and divides the wafer into individual device chips. The picking-up step picks up the individual device chips from the polyolefin-based sheet.SELECTED DRAWING: Figure 4
